Updating only metadata of an object in SoftLayer using jclouds API

Question

I want to update only the metadata of an object stored in SoftLayer using the jclouds API. The object already exists so don't want to upload it again.

Answer 1

Use a server-side copy to update metadata:

blobStore.copyBlob(containerName, blobName, containerName, blobName, CopyOptions.builder()
        .contentMetadata(...)
        .userMetadata(...)
        .build());
